I've been with my boyfriend for 16 months and we have lived together for over a year. We work great as a team and get along very well. When we first met I was madly and crazy in love with him. Obviously after a year of spending every moment with each other I still love him, but the whole "new and exciting" part has worn off. Sexually we are fine when we do get around to it, but we don't get around to it nearly as much as we use to. A lot of that is because I get pain during sex sometimes so I'm not really in the mood when I'm in pain. He takes care of himself when I am not available to do so, which doesn't make me worry much about it, but I still feel like that might be a problem in the future (yet if it's going to be a problem with anyone, he would most likely be the most understanding out of most guys).We pretty much act like a married couple. We do everything together, we have dinner together, we share a bank account, we have a puppy together, etc. How do i know if he's the one??
